Pro Insulation
This scene is used to detect indoor insulation anomalies of building
walls and ceilings. The required parameters include Indoor Temp.,
Outdoor Temp., and Insulation Level.
When indoor temperature is less than or equal to outdoor
temperature, regions with insulation levels surpassing the preset
12
threshold will be highlighted in cyan. Conversely, if indoor temperature
exceeds outdoor temperature, areas with insulation levels lower than
the preset value will be marked in cyan.
NOTE
Indoor Temp. represents the current indoor temperature.
Outdoor Temp. represents the current outdoor temperature.
Insulation Level: An integer ranging from 0 to 100. Typical values
for new buildings fall within 60–80%.
Pro Moisture
To detect potential indoor moisture issues, it is necessary to configure
Relative Humidity, Ambient Temp., and RH Threshold(%).
Regions with condensation deficiency will be highlighted in green when
the measured relative humidity surpasses the specified RH Threshold.
NOTE
Relative Humidity indicates the current relative humidity level.
Ambient Temperature indicates to the current atmospheric
temperature.
RH Threshold represents the humidity upper limit of the target
surface. A relative humidity of 100% signifies that water vapor
condenses into liquid water (dew point), while levels around 70%
or higher may promote mold growth.
Values of Relative Humidity and Ambient Temp. can be acquired
using hygrometers and thermometers, respectively.
Floor Heating
This scene is used to detect and monitoring faults in underfloor heating
systems.
UIRA-Scene technology enables rapid identification of irregularities
during floor heating inspections. Upon activation, if heat irregularities

10. Guidance for Common
Thermal Imaging Operations
The manual provides guidance on common issues for first-time users of
imagers. For other questions or updated guidance, please contact
technical support.
10.1 Can the UIRA-IR Algorithm Detect
Water Leaks or Insulation Issues with
100% Accuracy?
No. Although the UIRA-IR algorithm delivers reliable detection
performance, it does not achieve 100% accuracy. The algorithm is
designed for preliminary screening by analyzing thermal image
characteristics in various scenarios, based on clear images captured by
users. If an area is makred as "Suspect," we recommend manual
verification by professionals. Additionally, keeping your device’s
firmware updated ensures access to the latest algorithm
enhancements.
10.2 Factors may Interfere with the
Detection Results of UIRA-Scene
Different wall materials and surrounding heat sources
Heat diffusion properties of different wall materials:
Some wall materials exhibit heat diffusion patterns that resemble
common wall defects, making it necessary for experienced
professionals to conduct further verification.
Interference from ambient heat sources (e.g., heaters or air
conditioning vents):
External heat sources may cause localized temperature increases on
30
wall surfaces, affecting detection accuracy.
10.3 Improve Water Leak Detection
Success Rates
Method
1.
Adhere to recommended leak area and detection distance
guidelines. Ensure the leak area and detection distance match your
device’s IR resolution.
For example:
IR Resolution
Distance
Leak Area
96×96
≤ 1m
≥ 10cm×15cm
96×96
≤ 2m
≥ 20cm×30cm
256×192
≤ 2m
≥ 10cm×15cm
256×192
≤ 4m
≥ 20cm×30cm
Check your device’s IR resolution under Specification.
2.
Perform multiple inspections and dynamic comparisons:
Relying on a single thermal image may lead to errors. Compare images
taken at different times (e.g., day vs. night), under varying temperature
conditions, or from different angles. You can also observe the same
area dynamically.
10.4 Higher-Quality Image
How to Take Clear Thermal Imaging Pictures?
31
Principle
Thermal image use colors to show temperature distribution. The
temperature range of the target affects the image effect.
Method
1.
When the actual temperature difference of the target in the image is
higher than 10 °C (50 °F ) or 20 °C (68 °F ), the thermal image effect is
most obvious, which helps to highlight the subtle temperature
difference.
2.
When the temperature difference of the target in the image is small,
you can manually adjust the temperature range (if applicable) of the
whole image to increase the contrast of the target.
3.
It is recommended that the distance between the imager and the
target should be within 2 meters (about 6.56 feet). Adjust the
distance to ensure clear focus, especially for small targets.

10.5 Guidance on Using Thermal Imaging
for Common Water Leak Detection
Principle
Water has a higher specific heat capacity than building materials, so the
temperature change rate of the leaking area is different from that of
the surrounding materials. The thermal imager captures this
temperature difference to locate the leak point contactlessly.
Tips
1.
Best Testing Time Period: Choose sunrise or sunset for testing. At
this time, the temperature difference between indoors and outdoors
is usually over 10 °C (50 °F), and the solar radiation heat gradient
makes the thermal imaging of leak points inside the wall more
obvious.
32
2.
Environmental Condition Control: The surface temperature should
be tested in dry and sunny weather. Rain and snow will lower the
surface temperature and interfere with the infrared signal, which will
seriously affect the accuracy of detection.
3.
Priority Detection Area: Scan the weak links of building structures
such as wall corners, window and door edges, existing cracks, pipe-
through wall holes, and connections, which are high-risk areas for
structural water leakage and pipe water leakage.
4.
Dynamic Verification: Avoiding false alarms caused by single-time
capture results. In the periods with significant day and night
temperature differences, or after adjusting different angles to
capture the same area multiple times. Dynamic verification can be
used to exclude false alarms.
NOTE
Structural Leakage Test: Spraying water on the wall to simulate
wetting, or testing the residual water-stained area immediately
after rain, can enhance the temperature difference contrast.
Pipe Leakage Detection: For persistent water leakage, you need to
take pictures during periods of water pressure changes (such as
before and after peak water usage) and refer to the specific
suggestions for pipe leakage detection.
Micro Leakage: if the water leakage is very small and the
temperature difference is not obvious, it is recommended to use
devices with higher sensitivity and resolution (such as ≤40 mK
thermosensitivity and ≥256 × 192 resolution) to improve detection
rate.
10.6 Detect Water Pipe Leaks
How to Use Thermal Imaging for Hot Water Pipe Leaks?
Principle
When hot water pipes leak, heat energy will conduct to the surface of
buildings, and the leaked area will show as a high-temperature region
33
(usually in red or highlighted color) on the thermal image, which can
help you locate the leakage point.
Tips
1.
Time Selection: Select sunrise or sunset time when the environment
temperature changes significantly and helps to enhance the
temperature difference effect.
2.
Pressure Verification: Use the pipe pressure tester to monitor the
pressure change. If the pressure continues to decrease after
pressurization, it can be preliminarily confirmed that there is a leak.
3.
Temperature Difference Enhancement: Ensure the hot water
temperature is at least 10°C higher than the room temperature and
maintain the flow for 15-30 minutes. Under this condition, a
detectable temperature difference can be formed in concrete, wood
boards, or gypsum boards with a penetration depth of 3-5cm.
4.
Pathway Tracking: System scans along the hot water pipe route,
focusing on high-risk parts such as interfaces, valves, and wall-
penetrating holes, as well as historical maintenance records.
NOTE
The detection effect is influenced by water temperature (must be
10 °C higher than the indoor temperature), pipe burial depth
(concrete or dense materials over 5 cm deep may affect imaging), and
contact material (wooden boards or gypsum boards can be detected).
This method is applicable to contact heat transfer scenes. When
pipes have no physical contact with building structures or when
leakage water cannot penetrate to the surface, it will not be possible
to detect due to lack of temperature difference contrast.
How to Use Thermal Imaging for Detecting Leaks in Cold Water
Pipes?
34
Principle
Cold water leakage causes heat conduction to the wall, which results in
a lower temperature than that of the surroundings. The thermal imager
captures the temperature difference and displays it as a low-
temperature area (usually in blue).
Tips
1.
Time Selection: The temperature difference between cold water and
indoor temperature is usually small, and it is difficult for the
temperature to conduct to the surface. You can select sunrise or
sunset for testing, as the natural temperature difference can help
enhance the contrast.
2.
Pressure Verification: Use a pressurizing device to monitor the
pressure of the pipe. If the pressure continues to drop, it can help
confirm that a leak exists.
3.
Operation in Winter: After preheating the wall and floor in the
heating environment, continuously supply cold water to the cold
water pipe to create a significant temperature difference.
4.
Operation in Summer: Inject cold water into the cold water pipe
during the low-temperature sunrise hours to enhance the test effects
by leveraging the temperature difference between the environment
and the water.
5.
Temperature Difference Strengthening Method: Pour hot water
into the cold water pipe and keep it for 15 minutes (refer to the hot
water pipe testing tips), which can quickly generate a recognizable
temperature difference.
NOTE
The detection effect is influenced by water temperature (must be
10 °C higher than the indoor temperature), pipe burial depth
(concrete or dense materials over 5 cm deep may affect imaging), and
contact material (wooden boards or gypsum boards can be detected).
This method is applicable to contact heat transfer scenes. When
pipes have no physical contact with building structures or when
35
leakage water cannot penetrate to the surface, it will not be possible
to detect due to lack of temperature difference contrast.
10.7 Can the Thermal Imager Penetrate
Walls or Floors?
No. Thermal imagers cannot penetrate walls or floors like X-ray
machines. They can only detect heat emitted from the surface of an
object. However, in certain cases, the thermal imager can detect
anomalies inside walls or floors, such as water pipe leakage or heat loss
due to poor insulation. This is because the thermal imager can capture
the heat conducted to the surface of the wall or floor. If the pipe has no
contact with the wall or ground, the temperature cannot be conducted,
and the thermal imager cannot detect it.
10.8 Check a Thermal Imager’s
Temperature Accuracy
How to test the accuracy of the devices?
Tips
1.
Pour crushed ice and water into the cup, and turn on the imager.
2.
Mix the solution and let it stand for a few minutes.
3.
Set the imager's emissivity to 0.95 and adjust the distance.
4.
Point the imager at the solution to measure its temperature. To get
the best effect, please measure the temperature of water surface and
avoid measuring cup wall. The reading should be close to the freezing
point (0 °C / 32 °F) and within the precision range.
36
10.9 Frozen Images
What are the clicking sound and frozen image after device startup?
This is a normal phenomenon of the thermal imaging device. To keep
the measurement accuracy, the imager will automatically calibrate the
environment temperature change. During this process, the screen may
stutter and show "Image Calibrating…", and you can also hear a "click"
sound from the device. This phenomenon usually occurs when the
imager is moved quickly or when it is turned on for the first time.
10.10 Prolong Battery Life
How to extend the life of lithium batteries?
Tips
1.
Initial Charging: Charge the device for 3 hours in the off state before
first use.
2.
Charging Cable: Use the included charging cable or an authenticated
one.
3.
Power Adapter: For best results, use a standard 5 V/2 A charger.
4.
Storage and Reuse: When storing the device for a long time, charge
it to full capacity every 3 months. Before using the device after
storage, turn off the device and charge it for at least 30 minutes.
